 a blood viscosity measurement assembly that measures a blood viscosity which is supplied from the blood sample injector; and 
 a data processor that analyzes a value which is measured by the blood viscosity measurement assembly, and calculates the blood viscosity, 
 wherein the blood viscosity measurement assembly includes:
 a cartridge that is detachably attached to the case and includes two vertical support portions, wherein each of the two vertical support portions defines a space therein and the two vertical support portions are connected to the cartridge to form a U-shape; 
 a lower connector that is mounted on the two vertical support portions; 
 a first vertical tube and a second vertical tube that are capable of being respectively inserted into the space of the two vertical support portions; 
 a capillary tube that is inserted into the lower connector; 
 an auxiliary tube path that is formed in the lower connector and connects the second vertical tube to the capillary tube; 
 a valve which is disposed in the lower connector, supplies the blood that is supplied from the blood sample injector to the first vertical tube, and causes the blood that is flowed into the first vertical tube to be supplied to the capillary tube, wherein the valve has a configuration to change a flow path and supplies the blood from the first and second vertical tubes and the capillary tube to the blood sample injector, and 
 a first sensor and a second sensor that are disposed adjacent to the first and second vertical tubes and sense a position of the blood in the first and second vertical tubes, respectively. 
 
 
     
     
       2. The portable blood viscosity measurement apparatus of  claim 1 , wherein the two vertical support portions respectively include incising portion and visually identify heights of the blood in the first and second vertical tubes. 
     
     
       3. The portable blood viscosity measurement apparatus of  claim 1 , further comprising:
 a cartridge transport assembly that comes into close contact with the cartridge or the lower connector, and transports the cartridge and the lower connector to be protruded from the case. 
 
     
     
       4. The portable blood viscosity measurement apparatus of  claim 1 , wherein the case includes an upper case and a lower case which are installed in a foldable manner, and wherein the case further comprises a support portion that is disposed between the upper case and the lower case and the upper case is supported perpendicularly to the lower case. 
     
     
       5. The portable blood viscosity measurement apparatus of  claim 1 , further comprising:
 a barcode recognition assembly that recognizes a barcode which is attached to the blood sample container or the lower connector and that transmits the recognized data to the data processor. 
 
     
     
       6. The portable blood viscosity measurement apparatus of  claim 1 , further comprising:
 a heater that is installed in the case, is disposed on a rear surface of the cartridge, and supplies heat to the cartridge. 
 
     
     
       7. The portable blood viscosity measurement apparatus of  claim 6 , wherein the heater includes:
 a heat generation assembly that generates heat; and 
 a heat supply tube that is disposed in a shape corresponding to the two vertical support portions of the cartridge. 
 
     
     
       8. The portable blood viscosity measurement apparatus of  claim 7 , wherein the two vertical support portions include predetermined regions which are disposed to face the heater and are incised to receive the heat from the heater. 
     
     
       9. The portable blood viscosity measurement apparatus of  claim 1 , wherein the blood sample injector includes:
 a container mounting portion on which the blood sample container is mounted; 
 a needle assembly that includes a first needle and a second needle which are inserted into the blood sample container; 
 a pump that provides a pneumatic pressure to the first needle; and 
 a rotation portion that periodically rotates the container mounting portion and the needle portion at a predetermined angle. 
 
     
     
       10. The portable blood viscosity measurement apparatus of  claim 9 , further comprising:
 a connection tube that is disposed in the case and connects the second needle to the valve. 
 
     
     
       11. The portable blood viscosity measurement apparatus of  claim 10 , wherein the data processor controls the pump, the rotation portion, and the valve, operates the rotation portion to mix the blood in the blood sample container if the blood sample container is mounted on the container mounting portion, drives the pump and injects air into the blood sample container through the first needle and controls that the blood is supplied to the valve through the second needle, and rotates the valve and connects the first vertical tube and the connection tube before the pump is driven. 
     
     
       12. The portable blood viscosity measurement apparatus of  claim 1 , further comprising:
 a level meter that measures a horizontal level of the case with respect to a floor. 
 
     
     
       13. The portable blood viscosity measurement apparatus of  claim 12 , further comprising:
 at least three horizontal adjustment assemblies that are installed in the case to support the case on the floor, and whose heights are configured to be changed.
